Owners of wireless headsets often face a situation when beloved Xiaomi Basic 2 stop responding to commands or play audio. This can happen at the most inopportune time: while calling or listening to music in transport. The main difficulty is that the symptoms can be different, from the complete absence of sound in one of the channels to the inability to connect to a smartphone.
Before you bring a device to a service center or buy a new pair, you need to conduct a thorough diagnosis yourself. Often the problem is not a breakdown of the speakers, but a software failure or contamination of the contacts. In this article, we will analyze all possible causes of malfunctions and offer step-by-step instructions for fixing them so that you can return functionality to the gadget.
Restoring True Wireless headsets requires careful attention to detail, sometimes a simple reboot is enough, and other times it will require resetting to factory settings. Understanding how Bluetooth protocols and charging cases work will help you find the root of the problem faster.
Problems with Bluetooth connection
The most common situation when headphones don't work is due to pairing protocols, devices may not see each other or permanently lose connection, often due to overcrowded Bluetooth memory on the phone or interference on the air.
If the Xiaomi Basic 2 isn't connected, the first thing you need to do is remove the old pairing. Go to the Bluetooth settings on your smartphone, find your model in the list of devices, and select the option "Forget the device" or "Unpair the pairing." Then you need to turn off the Bluetooth on your phone, put the headphones in the case and close it for 10 seconds.
Then you re-pair, and you take both of the headphones out of the case at the same time, and they have to go into search mode, which is signaled by the flashing of the indicators, and if that doesn't happen, maybe one channel has forgotten the other.
- 🔴 The indicator flashes red and white – the process of searching for a device or trying to connect.
- 🔵 The indicator is lit blue – the connection is successfully installed, data is transmitted.
- ⚪ The indicator does not burn - the battery is discharged or the device is turned off.
- 🟣 Blinking on only one headphone - desynchronization of channels (TWS error).
It is important to consider that the range of Bluetooth is limited, if the phone is in a distant pocket or behind a thick wall, the signal can be interrupted, and interference can create working microwave ovens or Wi-Fi routers operating at 2.4 GHz.
The lack of sound in one of the headphones
The situation when only one Xiaomi Basic 2 is working is classic for TWS (True Wireless Stereo) technology. Often users think that the speaker is burned, but in 80% of cases the problem lies in the desynchronization of the left and right channels.
To fix the problem, you need to perform a full reset. Put both earbuds in the charging case. Make sure they are installed correctly and the contacts touch. Without closing the lid, press and hold the touch zones on both earbuds simultaneously for 10-15 seconds.
⚠️ Warning: During reset, the indicators may flash red several times. Do not let your fingers go until you see a triple blink or a change in color to white/blue, which signals the completion of the procedure.
Once reset, you need to remove the device from the Bluetooth list on the phone again and pair it again. If the sound appears but quickly disappears again, check the sound balance in the settings of the special features of your smartphone. Sometimes the system slider shifts towards one channel.
If software methods don't work, it's worth checking the physical integrity of the audio mesh. Earwax and dust can completely block the speaker hole, creating the illusion of a breakdown. Carefully clean the mesh with a dry soft brush or cotton swab dipped in alcohol (without pouring in).
☑️ Diagnostics of sound
Headphones are not charged or the case does not see the device
Failure to charge is a critical problem that renders the Xiaomi Basic 2 useless, most often oxidized contacts are to blame, metal headphones and inside the case eventually form a plaque that prevents the flow of current.
To clean, use a cotton swab dipped in isopropyl alcohol or a dry toothbrush. Carefully wipe the contacts on the headphones themselves and the pins inside the recesses of the case. Sometimes the problem lies in the protective film that was forgotten to remove from the new headphones on the contacts.
| Status of the indicator | Possible cause | Action. |
|---|---|---|
| Not burning in the case. | Case discharged or oxidized contacts | Charge the case, clear the contacts. |
| Blinks red. | Charging is in progress. | Leave for 30-60 minutes. |
| It burns red all the time. | Battery error or overheating | Cool the device, change the cable |
| Burning white/blue | Charging complete (100%) | We can use it. |
It's also worth checking the charging cable and the power supply. Using too powerful units (Fast Charge over 18W) sometimes causes the power controller to react protectively in cheap models, and charging does not work. USB-port of the computer or old block on 5B 1A.
If the case is charging, but the headphones inside don't light up, maybe they're just not fully inserted into the sockets. The magnets should tightly pull the headphones. Try pressing them lightly with your finger and see if the light goes on.
Why can’t you use wireless charging for a case?
Silent sound or distortion of audio
If the headphones are working, but the sound has become quiet, deaf or wheezing, the problem may be codec or contamination. In Bluetooth settings on Android, you can often select the transmission codec (SBC, AAC, aptX). Try switching them to see if the quality changes.
Grid pollution is the second most common cause of silent sound. Even a microscopic layer of fat and dust works like a sound insulator. Use a special cleaning gel or soft brush for careful cleaning. Don't use sharp objects to avoid piercing the speaker membrane.
Distortions can occur when battery power is low. When the charge level drops below 15%, the amplifier inside the Xiaomi Basic 2 may not give enough power, leading to "wheezing" on the bass. Charge the device to 100% and check the sound again.
Also check the equalizer settings in the Mi Music app or third-party players. Sometimes activating Volume Sound or Bass Boost at maximum causes clipping, which sounds like a crack.
Sensory control is not responding
Sensors on Xiaomi Basic 2 may stop responding to touch due to moisture or software errors. If you exercised and your headphones got wet with sweat, the touchpad may not behave properly because the water conducts current.
In this case, wipe the headphones dry and allow them to dry completely at room temperature.Do not use a hair dryer or heaters, as high temperatures can damage the glue that holds the case together.
⚠️ Warning: If the sensor is stuck (constantly pausing tracks or turning on the assistant), put the headphones in the case and close the lid for 5 minutes.
In rare cases, gesture reconfiguration is required via the Mi Wear app or Xiaomi Earbuds. Make sure the app doesn't need to turn off the sensor for a specific action (like a double tap).
💡
To make the sensor work better, touch the area with a confident but not strong press. The pald slide on the surface is often not recognized, you need a clear tap.
Hardware malfunctions and battery wear
If none of the software methods worked, there is probably a hardware breakdown, which could be a battery failure that has lost capacity and no longer holds charge even after the contacts have been replaced.
Inside the Xiaomi Basic 2, tiny lithium-polymer batteries are used. Over time (after 2-3 years of active use), they degrade.Symptom is the work of the headphones only during charging or shutdown 5-10 minutes after full charge.
There may also be mechanical damage after a fall, which can unplug the speaker plume or disrupt soldering inside the casing, and in such cases, self-repair is extremely difficult due to the monolithic design and lack of spare parts available for sale.
- 🔋 Battery lasts less than 30 minutes – it requires replacement of the element.
- 🔊 Wheezing at any volume level - damage to the speaker membrane.
- 📡 Not included at all – a deep discharge or a chain break.
- 💧 The moisture indicator (if any) changed color - the ingress of liquid.
In case of hardware problems, it is more economically feasible to purchase a new model, since the cost of repairs with battery replacement and restoration of leakage may exceed the price of a new device.
💡
If the headphones do not respond to charging for more than 30 minutes and do not show an indication, most likely, the battery has gone into a deep discharge or the power controller has failed.
